The non-proliferative
nature of adult cardiomyocytes precludes the possibility of endogenous
repair of the heart muscle following a myocardial infarction. Additionally,
there are currently no definitive therapies to improve or prevent
deterioration of cardiac function following an infarction. Cellular
cardiomyoplasty has met with limited success and has the potential
to be arrhythmogenic. My efforts focus on the creation of an engineered
3-D cardiac "tissue" with native cellular orientation,
electrical propagation, and mechanical contraction. Cardiac constructs
will be cultured in a novel bioreactor that delivers mechanical
impulses to neonatal rat cardiomyocytes in hydrogel scaffolds. These
cardiac constructs can be used to study various pathological states
in vitro and may have potential therapeutic applications in the
future.
